Models with partial compositeness, like composite Higgs models or models with a warped extra dimension, generically predict tree-level corrections to electroweak precision observables and flavour-changing neutral currents. I will discuss flavour constraints on this class of models, considering several choices for the electroweak representations and comparing flavour-symmetric models to...

A combined fit of electroweak precision data and data on Higgs decays lead to an exclusion of the Standard Model with a sequential fourth generation at the level of 5 standard deviations. In my talk I discuss the methodology of the corresponding statistical analysis, which involved so-called non-tested hypotheses. Then I discuss a supersymmetric GUT model, in which the atmospheric...
